A Generalized Model for Describing Particle Formation in the Synthesis of Monodisperse Oxide Particles Based on the Hydrolysis and Condensation of Tetraethyl Orthosilicate

Preparation of Ordered Macroporous Platinum Metal Particles

“…The sizes of silica spheres (the distance between the centers of adjacent spheres) prepared using ammonia and methylamine were 520 and 260 nm, and the surface area values were 7.6 and 15.8 m 2 g −1 , respectively. Surface area values were roughly corresponding to the calculated ones (6.1 and 12.2 m 2 g −1 ) based on the diameters (520 and 260 nm) and the density of silica spheres (1.87 g cm −3 ) [17]. SEM images and the surface area values indicate that silica spheres were nonporous.…”

Preparation of silica–polystyrene core–shell particles up to micron sizes

“…TEOS molar concentrations in Table 1 were calculated with reference to ethanol only. In the preparation of the large particles (sample D) in Table 1, CH 3 COOH was added to the system, as an increase in ionic strength increases resultant particle sizes in the hydrolysis of TEOS and is effective in suppressing generation of new particles in the seeded growth reaction [30,31].…”

Deposition of gold nanoparticles on silica spheres by electroless metal plating technique

“…Monodisperse colloidal silica (SiO 2 ) spheres were prepared by a sol-gel method according to our previous papers [17,18]. A mixture of the methylamine solution (4.66 g), water (56.8 g), and ethanol (83.18 g) was placed in a water bath at 35 • C. Then the mixture was transferred to a flask that contained the TEOS (12.5 g) and the ethanol (100 g) at 35 • C under stirring.…”
